26、initial, start of life dimensional, optical, mechanical and environmental performance requirements which a terminated and assembled singlemode resilient alignment sleeve LC-PC duplex connector set (plug / adaptor / plug) must meet in order for it to be categorised as an European Standard product. Si
27、nce different variants and grades of performance are permitted, product marking details are given in 3.5. 1.2 Intermateability Although all products conforming to the requirements of this European Standard will intermate, the resulting level of random attenuation performance will only be ensured in
28、accordance with Table 1. The intention is that this will be true irrespective of the manufacturing source(s) of the product. In all cases, the intermating of plug variants having different attenuation or return loss grades will result in an uncertain level of random attenuation performance. When int
29、ermating plug variants having different return loss grades, the resulting level of return loss can not be assured to be any better than the worst return loss grade. Similarly, the intermating of a grade P plug with a grade Q plug will result in an uncertain level of random attenuation performance. T

32、 20 years, compliance with this European Standard does not guarantee the reliability of the product. This should be predicted using a recognised reliability assessment programme. 1.5 Quality assurance Compliance with this European Standard does not guarantee the manufacturing consistency of the prod
33、uct. This should be maintained using a recognised quality assurance programme.

41、0377-7-2:2004 3 Description The LC-PC duplex connector is a single position plug connector set of plug adaptor plug configuration characterised by cylindrical, spring loaded butting ferrules of 1,25 mm nominal diameter and a latched push-pull coupling mechanism. The optical alignment mechanism of th
42、e connectors is of a resilient sleeve style. 3.1 Plug The plug features a cylindrical zirconia ceramic ferrule and a latched push-pull mechanism. It has a single male key which is used to limit and may be used to orientate, the relative rotation between mated connectors. A cover (dust cap) to protec
43、t the ferrule endface when the connector is in the unmated condition shall be provided. Alternative materials may be used for the ferrule that have directly compatible material properties to zirconia but the endface and performance requirements must be met under all conditions 3.2 Adaptor The adapto
44、r has a zirconia ceramic resilient alignment sleeve. The mounting style is duplex rectangular flange equipped with snap-latches. Covers (dust caps) shall be provided to protect each port of the adaptor. Alternative materials may be used for the sleeve that have directly compatible material propertie
45、s to zirconia but the performance requirements must be met under all conditions 3.3 Materials Materials which are not specified or which are not specifically described are left to the discretion of the manufacturer. 3.4 Dimensions Outline dimensions and other dimensions necessary to ensure intermate
46、ability or which affect performance are specified. All other dimensions are left to the discretion of the manufacturer. Where the mating face limit dimensions are not in agreement with an IEC interface standard this is clearly stated. 3.5 Colour and marking Marking of the product shall be in accorda
47、nce with 2.6.2 of EN 186 000-1 in the following order of precedence: a) identification of manufacturer; b) manufacturing date code : year/week; c) manufacturers part number; d) variant identification number.
